Does anyone have any answer for the original question about a workaround to be able to mount bolt on wheel simulators versus the frisbee style snap in wheel simulators?
They make chrome simulators that your nuts hold on and then a cap is held on by screws! My new Greyhawk has knock on caps with valve attached to hub cap.
I think I'll replace the two large flanged lug nuts with ones that are used on a Hummer. Same size stud but the flanged nut height is about 1/4 inch shorter. It should leave 6-8 threads visible to screw the adapters on. Part number is Dormant 611-054
